Is it possible to standardize types in an interface?

Question

export interface BookProps {
  link: string;
  title: string;
  image: string;
  author: string;
  discount: string;
  publisher: string;
  description: string;
}

Is there a way to express that all elements in the interface have a string type in a concise manner?

Answer 1

You could use index properties to achieve a general interface definition.

interface Book {
    [prop: string]: string;
}

const nineteenEightyFour: Book = {
    link: "https://...",
    title: "nineteenEightyFour",
    .... 
}

Ts should be happy enough with this.
